Hydraulic Unit Materials (1)

Hydraulic units are systems that work by directing fluids under pressure. These units are used in a wide range of applications, from industrial machines to automotive systems. The use of the correct materials is essential for the efficient operation of hydraulic units. These materials should be selected to ensure the safety, durability, and efficiency of the system.

Hydraulic Unit Materials: Overview

A hydraulic unit consists of various components used to control, direct, and convert the pressure in fluids into power. The materials used for these systems must be capable of withstanding high pressure and challenging operating conditions. The main materials used in hydraulic units include pumps, valves, hoses, cylinders, filters, and oils.

1. Hydraulic Pump

Hydraulic pumps are components that move fluid under pressure and convert energy into mechanical work. These pumps maintain the fluid in the system at a specific pressure, providing hydraulic power.

• Applications: Industrial machinery, construction equipment, automotive hydraulic systems.

• Material Properties: Requires high durability and wear resistance. Mostly made from steel and cast iron.

2. Hydraulic Valves

Hydraulic valves control the direction, speed, and pressure of fluids. These valves ensure the proper direction of hydraulic flow and the efficient operation of the system.

• Applications: Industrial automation, automotive, heavy-duty machinery.

• Material Properties: Valves are usually made of high-pressure resistant steel alloys and equipped with seals that provide leakage protection.

3. Hydraulic Cylinders

Hydraulic cylinders convert hydraulic energy into linear motion. The fluid is pumped into the cylinder, moving the pistons, which transfer this motion outward.

• Applications: Various industrial machinery, construction equipment, vehicles.

• Material Properties: Cylindrical structures are generally made of steel. Durable alloys and sealing elements are required for pistons.

4. Hydraulic Hoses and Pipes

Hydraulic hoses carry the fluid in the system and are usually made to withstand high pressure. Hoses are made of flexible and durable materials. Pipes, on the other hand, carry the fluid through fixed lines.

• Applications: All hydraulic systems, especially heavy machinery.

• Material Properties: Generally made of durable materials such as steel, stainless steel, and rubber. They must be resistant to high pressure and flexible.

5. Hydraulic Filters

Filters remove dirt, rust, and other foreign particles in hydraulic systems to ensure proper operation. Dirty fluid can damage system components, making filters essential.

• Applications: All hydraulic systems, especially those requiring long-term operation.

• Material Properties: Filter elements are usually made of metal or high-quality synthetic materials. They should be highly efficient and long-lasting.

6. Hydraulic Oils and Fluids

Hydraulic oils are used as a substance that allows fluids to move under pressure and prevents system wear. Additionally, oils provide cooling and sealing functions.

• Applications: All hydraulic systems, especially machines and heavy-duty machinery.

• Material Properties: The viscosity, temperature resistance, and anti-wear properties of oils are crucial. Generally, mineral oils, synthetic oils, or biologically soluble oils are used.

7. Hydraulic Seals

Seals are used to provide sealing in hydraulic systems. These components ensure that the fluid moves only in the desired directions and does not leak outward.

• Applications: All hydraulic systems.

• Material Properties: Generally made of rubber, rubber, PTFE, or metal alloys. They must be resistant to high temperatures and pressures.

8. Hydraulic Tanks

Tanks store hydraulic fluids and ensure smooth flow in the system. These units monitor the fluid level and store excess fluid.

• Applications: Industrial machinery, construction equipment, automotive sector.

• Material Properties: Generally made of metal alloys, with a focus on sealing and safety.

9. Hydraulic Assembly and Connection Elements

Assembly elements ensure that all components are connected to each other. These elements ensure that the connections in the system are safe and durable.

• Applications: All hydraulic systems.

• Material Properties: Durable materials such as steel, stainless steel, or aluminum are used.

Properties of Hydraulic Unit Materials

Hydraulic unit materials must be resistant to challenging conditions such as high pressure, wear, corrosion, and high temperatures. The main characteristics that these materials must have are as follows:

• High Durability: Hydraulic systems generally operate under harsh conditions, so the materials used must be durable.

• Wear Resistance: Components such as pumps, valves, and hoses are in constant motion, so they need to be resistant to wear.

• Corrosion Resistance: Especially in humid environments, materials are used to prevent corrosion such as stainless steel or coatings.

• Heat Resistance: Hydraulic fluids can be exposed to high temperatures. Materials must be heat resistant.

• Flexibility and Sealing: Components such as hoses and seals must be flexible and designed to prevent leaks.
